摘要： A fixing device includes a fixing rotator rotatable in a rotation direction, a heat source to heat the fixing rotator, a pressure rotator contacting the fixing rotator, a nip formation pad to form a fixing nip between the fixing rotator and the pressure rotator, a slide sheet, and an adhesive part. The slide sheet between the fixing rotator and the nip formation pad contacts an inner circumferential face of the fixing rotator. The slide sheet has a center part and both end parts in an axial direction orthogonal to the rotation direction. The adhesive part bonds the slide sheet to the nip formation pad. The adhesive part includes a first adhesive part on the center part and a second adhesive part on one of the end parts. The first adhesive part has a first area, and the second adhesive part has a second area smaller than the first area.

摘要： An image forming apparatus includes an image forming section, a fixing device, and circuitry. The image forming section forms an image on a recording medium. The fixing device includes a rotator including a flexible endless belt, a pressure rotator pressed against the rotator to form a nip between the rotator and the pressure rotator, a heater heating the rotator, and a movable shield. The movable shield is disposed between the heater and the rotator to shield the rotator from radiant heat generated from the heater and is movable according to a size of the recording medium. The circuitry is configured to control the image forming section to form the image on the recording medium based on an image forming condition and change at least one of an operating temperature of the movable shield or a shielding amount of the movable shield based on the image forming condition.

摘要： A fixing device includes a first rotator and a second rotator that form a nip therebetween and fix an image on a recording medium that enters the nip. A heater heats at least one of the first rotator or the second rotator. A controller controls the heater to switch between a first heating and a second heating, to switch from the first heating to the second heating before the recording medium enters the nip, to start the second heating at a time prior to a nip entry time at which the recording medium enters the nip by a delay time period taken for the heater to conduct heat to the nip, and to continue the first heating before the second heating for at least one control cycle at a duty cycle of power supplied to the heater. The duty cycle is not greater than 40%.

摘要： A fixing device includes an endless fixing rotator, a slide aid, a pressure rotator, a nip formation plate, a support, a heat source, and a reflector. The endless fixing rotator has flexibility. An inner circumferential surface of the fixing rotator slides over the slide aid. The pressure rotator contacts an outer circumferential surface of the fixing rotator. The nip formation plate is disposed inside the fixing rotator to contact the pressure rotator via the fixing rotator and the slide aid to form a nip between the fixing rotator and the pressure rotator. The nip formation plate has a thermal conductivity equal to or greater than 10 W/mK. The support supports the nip formation plate. The heat source is disposed inside the fixing rotator to heat the fixing rotator. The reflector reflects radiant heat from the heat source.

摘要： A nip former that forms a nip between an endless belt and a pressure rotator includes a base that is made of aluminum and has a nip forming face disposed opposite the nip. An anodic oxidation coating is treated with sealing and coats at least the nip forming face. The anodic oxidation coating has a thickness that is not smaller than 22 μm and is not greater than 45 μm and a variation in thickness that is not greater than 20 percent. The base and the anodic oxidation coating define a nip forming portion that is disposed opposite the nip. The nip forming portion has a thickness that is not smaller than 0.40 mm and is not greater than 1.20 mm.
